What is a process by which organisms with characteristic suited to the environment will survive and reproduce

BartSMP [9]

According to Charles Darwin's theory of Evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

How is the chromosome number reduced between meiosis I and meiosis II? a. crossing over c. two replications b. metaphase d. no r

solniwko [45]

The answer is; B

During metaphase I of Meiosis I , homologous sister chromosomes line up the metaphase plate in pairs. During anaphase I, the sister chromosomes of the pairs are separated and move to opposite poles. This way, the resulting daughter cells have half the chromosome number as the parent cell.

How many food calories can a human burn up in an hour by exercising at this rate? (remember that only 20.0 % of the food energy

blsea [12.9K]

Human can produce a maximum mechanical power of 1/3 hp (horse-power).

Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)

So:

1 ph = 746 watt = 746 J/s

1/3 ph = 248.6 J/s

we're looking for the calories, so

1 joule = 0.239006 calories

So human produce a maximum mechanical power of:

248.6 J/s = 82.88 calories per second.

We're looking for the number of calories consumed in three hours, so:

82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).

The number of food calories is 895.2 food calories

Some scientists are studying a newly discovered microbe and determine that it consists of a single cell, lacking a nucleus. this organism could be <u>a bacterium.</u>

<u></u>

<h3>What do you mean by bacterium?</h3>

Any of a large group of one-celled organisms that reproduce by fission or by generating spores, lack a cell nucleus, and occasionally cause disease.
They are the most prevalent life forms on Earth, present in all living organisms as well as all climatic conditions.

<h3>What can be discovered in bacteria?</h3>

Its gel-like matrix, which also contains other cell components like ribosomes, chromosomes, and plasmids, is made up of water, enzymes, nutrients, waste products, and gases.
The cytoplasm and all of its elements are enclosed by the cell membrane.
Bacteria do not have a nucleus that is contained in a membrane like eukaryotic (true) cells do.
